本文描述了劳伦斯利弗莫尔国家实验室在激光触发光导开关的雪崩模式操作方面所做的工作。我们已经能够产生幅度为2kv - 35kv，上升时间为300 - 500ps的脉冲，并且开关增益（输出电脉冲的能量与触发光脉冲的能量）为10/sup 3/至10/sup 5/以上。两种不同的物理结构和两种不同的照明波长（1.06 /spl mu/m, 890 nm）的开关表现出非常相似的行为。因此，雪崩开关行为似乎与材料参数有关，而不是光学波长或开关几何形状。为了充分描述和理解这种操作模式，还需要做大量的进一步工作。
This paper describes work being done at Lawrence Livermore National Laboratory on the avalanche mode of operation of laser triggered photoconductive switches. We have been able to generate pulses with amplitudes of 2 kV - 35 kV and rise times of 300 - 500 ps, and with a switching gain (energy of output electrical pulse vs energy of trigger optical pulse) of 10/sup 3/ to over 10/sup 5/. Switches with two very different physical configurations and with two different illumination wavelengths (1.06 /spl mu/m, 890 nm) exhibit very similar behavior. The avalanche switching behavior, therefore, appears to be related to the material parameters rather than the optical wavelength or switch geometry. Considerable further work needs to be done to fully characterize and understand this mode of operation.
